(Recommend yourself to the Souls in Purgatory and mention your intentions here)

Blessed Souls, I have prayed for thee;I entreat thee, who are so dear to God,and who are secure of never losing Him,to pray for me a miserable sinner,who is in danger of being damned,and of losing God forever. Amen.

St. Alphonsus Liguori (1697-1787), from his Novena for the Holy Souls in Purgatory
